Storage device access system, method and device for secret stealing demonstration and medium

The invention discloses a storage device access system, method and device for secret stealing demonstration and a medium, mainly relates to the technical field of secret stealing demonstration, and is used for solving the problem that existing secret stealing demonstration equipment cannot carry out secret stealing demonstration at a computer end only supporting special USB flash disk access. Comprising a security chip and a storage chip, and the security chip is internally provided with an instruction transmission module supporting transmission of a first protocol and an instruction analysis module for analyzing a preset first protocol instruction; when secret stealing demonstration equipment is ready at the computer end; the secret stealing demonstration software reads the computer end file, adds the computer end file to the first protocol data write-in instruction after the computer end file is selected, sends the first protocol data write-in instruction to the secret stealing demonstration equipment, and
